概括

儿童心脏骤停后通过动脉旋转标记MRI测量的大脑血流 (CBF) 与患者的结果有关. 大脑和特定区域中较高的CBF与较差的神经状态相关.

科学领域:

神经学神经学
儿科重症监护中心儿童重症监护中心
医疗成像医学成像

背景情况:

脑血流 (CBF) 调节在心脏骤停后经常受到干扰.
逮捕后的CBF与儿童的神经结果之间的关系尚未得到充分理解.

研究的目的:

调查使用动脉旋转标记 (ASL) MRI 测量的 CBF 与心脏骤停后儿科患者的神经结果之间的关联.

主要方法:

一项回顾性观察性研究分析了48名儿科患者 (≤18岁),他们在心脏骤停7天内接受脑MRI.
在整个大脑和特定感兴趣区域使用脉冲ASL量化脑血流 (CBF).
通过使用儿科大脑性能类别 (PCPC) 评估神经结果,不良状态定义为变化≥1和PCPC排放3-6的不良状态.

主要成果:

具有不良神经结果的患者表现出明显更高的全脑CBF (28.3毫升/100克/分钟),与具有良好的结果 (19.6毫升/100克/分钟) 的患者相比.
增加CBF和不良结果之间的这种关联在各个大脑区域中是一致的.
逻辑回归,控制年龄,性别和MRI的时间,显示较高的CBF独立预测不良结果 (整个大脑的aOR 19.08).

结论:

动脉旋转标记MRI可以量化儿童心脏骤停幸存者的脑血流 (CBF).
逮捕后3-5天测量的CBF是儿童神经结果的独立预测指标.
儿科心脏骤停后CBF升高与不利的神经状态有关.

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
